[SOLVED] Making A Hammer to break a 3X3 Block. Breaking two layers at a time now.

[MinecraftDW2020]

I am trying to make a Hammer in 1.12.2.  I know, the regular, typical Hammer, once again in another mod. 
Overall I got the 3x3 Working, it breaks. Here is the code:

	public EnumActionResult onItemUse(EntityPlayer player, World worldIn, BlockPos pos, EnumHand hand,
			EnumFacing facing, float hitX, float hitY, float hitZ) {

		if (player.isSneaking()) {
			
			AxisAlignedBB grid = (new AxisAlignedBB(pos.getX(), pos.getY(), pos.getZ(), (pos.getX() + 3),
					(pos.getY() + 3), (pos.getZ() + 3)));
			for (int x = (int) grid.minX; x < (int) grid.maxX; x++) {
				for (int y = (int) grid.minY; y < (int) grid.maxY; y++) {
					for (int z = (int) grid.minZ; z < (int) grid.maxZ; z++) {
						BlockPos newpos = new BlockPos(x, y, z);
						if (worldIn.getBlockState(newpos).getBlock() != Blocks.AIR) {
							worldIn.destroyBlock(newpos, true);
						}
					}
				}
			}

			return EnumActionResult.PASS;

		} else if (!player.isSneaking()) {
			worldIn.destroyBlock(pos, true);

			return EnumActionResult.PASS;
		}
		return EnumActionResult.FAIL;
	}

However I have been messing around with it and I did not get it to work in the sense that I wanted, which is starting from the middle and breaking top,down, left and right.
I did try the top and down method. pos.up() pos.down() etc but that did not work when I did the whole facing checks. So it would be different for when I looked east, or when I looked north. I did fix that, but when I looked up or down, it did not.
I guess it was because it checked player Horizontal Plane for Direction..

 

Anyway Results Below:

 

 

Its starting from bottom left to top right.
I have been trying to get it into the middle block and it does it around

If you want to break only 9 blocks (and not 27) you need to know either:

a) which direction the player is facing 

b) which side of the block the player was aiming at

No, I got the breaking part to work. Just not the actual placement.

You mean, starting in the center?

Your problem is here:

 

AxisAlignedBB grid = (new AxisAlignedBB(pos.getX(), pos.getY(), pos.getZ(), (pos.getX() + 3),
					(pos.getY() + 3), (pos.getZ() + 3)));

 

You need to subtract 1 from the first three values and only add 1 to the last three. so the range is -1, 0, 1.

Well Thanks, That worked, it got to the middle but now it breaks two layer at a time, and I think it is because of the for loop, for the past 30 minutes I have been trying to get it to not do that, I tried changing the greater than signs around, messing around with min and max even more, and just doing other experimenting to it.

Well, you're breaking a 3x3x3 cube because of your offsets.

As I said, if I want a 3x3x1, you need to know either the facing of the player or the side that was hit so you can determine which of the three directions should be only 1 unit thick.

Yeah nevermind, I did that in my old method, got both confused, I decided to experiment with more on my old method instead and it felt much better. Not short but still remembered to do the facings.
Well now it is solved
